Thank you so much. I think a serious post-apocalyptic milieu could be done rather well sans zombies, mutants, monsters, and anything spookily supernatural. Man, having brought himself into such a state, would indeed continue to be the most dangerous game and would be more than enough of a auto-antagonist.
ehy, deep thoughts !! to tell the truth I never seriously stopped thinking about this, I always imagined a sort of umpteenth glaciation that hibernates all over the centuries, until once again nature wins with new shoots :-)) maybe it's too romantic a view! ! however of one thing you are absolutely right, man remains the greatest danger to himself. well, and after these inner and outer catastrophes ... I wish you a good Sunday !!
